Tony Tony Chopper / "Cotton Candy Lover"

Tony Tony Chopper (トニートニー・チョッパー) is the doctor of the Straw Hat Pirates. He is a reindeer that ate the Hito Hito no Mi and comes from Drum Island. Most of the time, Chopper is a toddler-sized human/reindeer hybrid, his devil fruit abilities allow him to change his appearance depending on the situation. Chopper's left antler has a metal plate wrapped around it at all times, from being broken in a fight when he was younger. Chopper also has a remarkable feature that no other reindeer have, and that is blue nose, while normal reindeers have black ones. As Oda's style evolved, Chopper has been given a more "chibi" appearance. This means that when in his Brain Point, Chopper has a larger head and eyes.
A running gag is that various characters in One Piece think Chopper is a tanuki (raccoon-dog, often simply translated as "raccoon") whilst in his Brain Point form. This is a play on the similar word "tonakai," the Japanese word for reindeer, from which the "Tony" in Chopper's name is derived. His heavy point form likewise is mistaken for a gorilla or an abominable snowman.
Lots of female characters find Chopper very cute such as Porche .
Oda has stated that he uses the color pink to represent Chopper, and (Oda was answering the questions as Chopper) for his smell, "how am I supposed to know?".
